Facts of the case (from oyez.org)
The Trump administration repealed the 2015 Clean Power Plan, which established guidelines for states to limit carbon dioxide emissions from power plants, and issued in its place the Affordable Clean Energy (ACE) Rule, which eliminated or deferred the guidelines. However, the U.S. Court of Appeals for the D.C. Circuit vacated the ACE Rule as arbitrary and capricious. One of the challengers, North American Coal Corporation, challenged the Environmental Protection Agency’s authority to so broadly regulate greenhouse gas emissions.

Question
Does the Environmental Protection Agency have the authority to regulate greenhouse gas emissions in virtually any industry, so long as it considers cost, non-air impacts, and energy requirements?

Conclusion
Congress did not grant the Environmental Protection Agency in Section 111(d) of the Clean Air Act the authority to devise emissions caps based on the generation shifting approach the Agency took in the Clean Power Plan.
Under the “major questions doctrine,” there are “extraordinary cases” in which the “history and the breadth of the authority that [the agency] has asserted,” and the “economic and political significance” of that assertion, provide a “reason to hesitate before concluding that Congress” meant to confer such authority. This is one such case, so the EPA must point to “clear congressional authorization” for the authority it claims. It cannot do so.
The EPA has admitted that issues of electricity transmission, distribution, and storage are not within its traditional expertise, yet it claims that Congress implicitly tasked it with the regulation of how Americans get their energy. Without “clear congressional authorization” for the EPA to regulate in such a manner, the agency lacks authority to implement the Clean Power Plan under the Clean Air Act.
